Invalidate entire namespace using Simple Spring Memcached

Angelo :

Has anyone tried invalidating an entire memcached namespace?

For example I have two reads methods having differents keys

@Override
@ReadThroughSingleCache(namespace = UrlClientExclusion.TABLE_NAME, expiration = 24 * HOUR)
public List<UrlClientExclusion> list(@ParameterValueKeyProvider String idClient) {

@Override
@ReadThroughSingleCache(namespace = UrlClientExclusion.TABLE_NAME, expiration = 24 * HOUR)
public UrlClientExclusion find(@ParameterValueKeyProvider int idUrlClientExclusion) {

and I want delete entire namespace UrlClientExclusion.TABLE_NAME on update/delete operation

I can't use a keylist method because there are many instances of the app

@InvalidateMultiCache(namespace = UrlClientExclusion.TABLE_NAME)
public int update(UrlClientExclusion urlClientExclusion, /*@ParameterValueKeyProvider List<Object> keylist*/ /* it is impossibile for me put all keys in this list*/) {

so the solution is to delete entire namespace.

What is the annototation to do this? It is possibible to build custom annotation to delete entire namespace? How?

Many thanks

Memcached doesn't support namespaces, SSM provides namespaces as a logic abstraction. It is not possible to flush all keys from given namespaces as memcached doesn't group keys into namespaces. Memcached support only flushing/removing single key or all keys.

You can flush all your data from memcached instance or need to provide exact keys that should be removed.
